Hypergraph Computation

open access: yesEngineering
Practical real-world scenarios such as the Internet, social networks, and biological networks present the challenges of data scarcity and complex correlations, which limit the applications of artificial intelligence. The graph structure is a typical tool

Spatiotemporal Fusion for Stock Prediction via Hypergraph Attention Gated Recurrent Units [PDF]

open access: yesEntropy
Stock prediction requires the joint modeling of temporal dynamics and cross-stock dependence. Existing graph-based and hypergraph-based forecasting methods often process spatial relation modeling and temporal evolution in separate stages, which may ...

Hypergraph Based Berge Hypergraphs [PDF]

open access: yesGraphs and Combinatorics, 2021
Fix a hypergraph $\mathcal{F}$. A hypergraph $\mathcal{H}$ is called a {\it Berge copy of $\mathcal{F}$} or {\it Berge-$\mathcal{F}$} if we can choose a subset of each hyperedge of $\mathcal{H}$ to obtain a copy of $\mathcal{F}$. A hypergraph $\mathcal{H}$ is {\it Berge-$\mathcal{F}$-free} if it does not contain a subhypergraph which is Berge copy of $\

On edge product hypergraphs [PDF]

open access: yesJournal of Hyperstructures, 2021
In this paper we introduced the notion of an edge product hypergraph. A hypergraph H is said to be an edge producthypergraph if edges of hypergraph can be labeled with distinct positive integers such that the product of all the labels of edges incident ...

Multimodal Data Fusion Algorithm Based on Hypergraph Regularization [PDF]

open access: yesJisuanji kexue, 2023
The multi-modal data fusion improves the performance of data classification and prediction by learning the correlation information and complementary information between multiple datasets.However,existing data fusion methods are based on feature pattern ...

Unavoidable Hypergraphs [PDF]

open access: yesJournal of Combinatorial Theory, Series B, 2021
The following very natural problem was raised by Chung and Erdős in the early 80's and has since been repeated a number of times. What is the minimum of the Turán number $\text{ex}(n,\mathcal{H})$ among all $r$-graphs $\mathcal{H}$ with a fixed number of edges?

On domination in an edge product hypergraphs [PDF]

open access: yesJournal of Hyperstructures, 2021
In this paper, we study domination in an edge product hypergraphs and found some results on it. It is proved that theunit edge in a unit edge product hypergraph is a dominating set of hypergraph H.

Unified Low-Rank Subspace Clustering with Dynamic Hypergraph for Hyperspectral Image

open access: yesRemote Sensing, 2021
Low-rank representation with hypergraph regularization has achieved great success in hyperspectral imagery, which can explore global structure, and further incorporate local information.

Quasirandomness in hypergraphs [PDF]

open access: yesElectronic Notes in Discrete Mathematics, 2017
An $n$-vertex graph $G$ of edge density $p$ is considered to be quasirandom if it shares several important properties with the random graph $G(n,p)$. A well-known theorem of Chung, Graham and Wilson states that many such `typical' properties are asymptotically equivalent and, thus, a graph $G$ possessing one such property automatically satisfies the ...

Infection in hypergraphs [PDF]

open access: yesDiscrete Applied Mathematics, 2018
In this paper a new parameter for hypergraphs called hypergraph infection is defined. This concept generalizes zero forcing in graphs to hypergraphs. The exact value of the infection number of complete and complete bipartite hypergraphs is determined. A formula for the infection number for interval hypergraphs and several families of cyclic hypergraphs
